What is your hardness in grains/gallon (gpg)?

To convert ppm or mg/l, divide by 17.1

What is your iron in ppm?

If over 5 ppm
- you need an iron filter.

Manganese in ppm?

Enter number of people?

I use 60 gallons/person/day:

Change if necessary

Extra gallons per day for horse etc.

Based on the information you entered,
is your Daily Grains of Capacity needed.
is the Total Grains of Capacity
you need for approximately once per week regeneration with a 24 hr reserve.
is the minimum cubic foot size of softener required for your capacity
needs.

To use the chart below, find the Salt Dose Capacity
that is closest to the above Total Grains
of Capacity needed. Round that up or down to the next
1000. That is the Capacity you will set your
control valve/softener for. You will program the salt
dose to the Salt Dose (total lbs)
above that figure. Then you will calendar override
for the number of days between regenerations.

If you have 2.0 ppm
or more of iron, you may want to regenerate every 3-4 days. If so divide the numbers you just produced by 2. Round
each up/down, they are your salt dose and capacity figures. Then you will
Calender Override the control at day 4. Depending on your iron content,
you may want to consider a softener with a Turbulator distributor tube
and/or SST-60 resin and to use a resin cleaner. Call Verizon cell 570-490-3201
or 1-800-326-8494 for prices.

This is the capacity
part of correctly sizing a softener, the SFR
is the other and much more important part...
